Martensitic grain qauv, ntawm qhov tod tes, muab lub zog siab, hardness, thiab hnav tsis kam. Txawm hais tias cov khoom no muaj txiaj ntsig zoo rau ntau daim ntawv thov, qee zaum lawv tuaj yeem ua rau txo qis ductility thiab toughness. Yog li ntawd, ua kom tiav qhov sib npaug ntawm qhov sib nqus permeability thiab martensitic grain qauv yog qhov tseem ceeb los xyuas kom meej qhov kev ua tau zoo hauv cov ntaub ntawv hlau.
2. Ferritic Composition thiab Magnetic Properties:
Ferritic steel, tus yam ntxwv los ntawm nws cov ntsiab lus siab chromium, muaj lub cev-centered cubic crystal qauv. Nws pom zoo heev corrosion kuj, siab ductility, thiab magnetic zog. Lub xub ntiag ntawm chromium nyob rau hauv ferritic hlau tsim ib tug tiv thaiv oxide txheej ntawm qhov chaw, muab kev tiv thaiv corrosion thiab oxidation. Cov khoom sib nqus ntawm ferritic steel tuaj yeem sib txawv nyob ntawm seb muaj pes tsawg leeg xws li alloy muaj pes tsawg leeg, kev kho cua sov, thiab kev ua haujlwm txias. Qee qhov xwm txheej, ferritic hlau tuaj yeem pom cov hlau nplaum sib nqus permeability, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau muaj kev tiv thaiv corrosion thiab cov khoom sib nqus.
3. Influence thiab Trade-offs:
Kev sib cuam tshuam ntawm kev sib nqus siab permeability, martensitic grain qauv, thiab ferritic muaj pes tsawg leeg hauv cov ntaub ntawv steel muaj qee yam kev lag luam tawm. Piv txwv li, kev ua tiav siab sib nqus permeability hauv cov ntaub ntawv hlau feem ntau yuav tsum tau siv cov khoom sib nqus mos, uas yuav muaj zog thiab hardness tsawg dua piv rau martensitic steels. Hloov pauv, martensitic grain qauv muab cov cuab yeej zoo heev tab sis tuaj yeem ua rau txo cov hlau nplaum permeability. Kev ntsuas qhov ntsuas no dhau los ua qhov tseem ceeb thaum xaiv cov khoom siv hlau rau cov ntawv thov tshwj xeeb.
Tsis tas li ntawd, muaj cov ferritic muaj pes tsawg leeg hauv cov ntaub ntawv hlau tuaj yeem cuam tshuam rau ob qho tib si sib nqus thiab corrosion kuj. Thaum ferritic steel muaj kev tiv thaiv corrosion zoo, nws tuaj yeem pom qhov sib nqus permeability qis dua piv rau cov khoom sib nqus mos. Yog li ntawd, ua tib zoo saib xyuas yog tsim nyog los xaiv cov hlau alloy tsim nyog uas ua tau raws li qhov xav tau ntawm ob qho tib si hlau nplaum thiab corrosion kuj.
